szha opened a new issue #18723: URL: https://github.com/apache/incubator-mxnet/issues/18723
## Description Currently the instructions for interactive shell with the test environment on CI for reproducing and debugging tests is not documented on cwiki or the website. The process involves: 1. observe the failed pipeline and examine the log to find the test  1. find the Jenkins file that corresponds to the failed pipeline in [ci/jenkins](https://github.com/apache/incubator-mxnet/tree/master/ci/jenkins). In this case it's [Jenkins_centos_gpu](https://github.com/apache/incubator-mxnet/blob/master/ci/jenkins/Jenkinsfile_centos_gpu) 1. find the failed test step in the Jenkins file, and the build step that produces the binary it uses. in this case the test step is https://github.com/apache/incubator-mxnet/blob/e2366e9102e6862416bf998af52baaa5e9c0a31b/ci/jenkins/Jenkinsfile_centos_gpu#L45 and its corresponding build step is https://github.com/apache/incubator-mxnet/blob/e2366e9102e6862416bf998af52baaa5e9c0a31b/ci/jenkins/Jenkinsfile_centos_gpu#L39 1. go to [ci/jenkins/Jenkins_steps.groovy](https://github.com/apache/incubator-mxnet/blob/master/ci/jenkins/Jenkins_steps.groovy) to find the corresponding build step https://github.com/apache/incubator-mxnet/blob/e2366e9102e6862416bf998af52baaa5e9c0a31b/ci/jenkins/Jenkins_steps.groovy#L733-L745 note down the docker and runtime function to invoke. in this case it's https://github.com/apache/incubator-mxnet/blob/e2366e9102e6862416bf998af52baaa5e9c0a31b/ci/jenkins/Jenkins_steps.groovy#L739 1. in the same file, find the test step https://github.com/apache/incubator-mxnet/blob/e2366e9102e6862416bf998af52baaa5e9c0a31b/ci/jenkins/Jenkins_steps.groovy#L1027-L1038 note down the docker and runtime function. in this case it's https://github.com/apache/incubator-mxnet/blob/e2366e9102e6862416bf998af52baaa5e9c0a31b/ci/jenkins/Jenkins_steps.groovy#L1033 1. run the command to trigger the build of the tested binary with the above docker name and runtime function. in this case the command should be: `ci/build.py --platform centos7_gpu_cu102 /work/runtime_functions.sh build_static_libmxnet cu102` 1. wait for the build to complete. afterwards, to run the complete test suite, run the test step command `ci/build.py --platform centos7_gpu_cu102 /work/runtime_functions.sh ci_package_pypi cu102` 1. to launch the interactive shell, we need to first locate the docker id from the docker files in [ci/docker](https://github.com/apache/incubator-mxnet/tree/master/ci/docker). in this case it's 1. with the docker id, run ``` docker run -it --rm -v $(PWD):/work/mxnet mxnetci/build.centos7_cpu:latest /bin/bash ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
